# What is BuyPerUnit?

BuyPerUnit is a free price-comparison index that ranks 6,546+ products by true cost per unit — $/GB for SSDs, hard drives, USB and SD cards and RAM, $/inch for TVs, and $/page for printer ink and toner — using prices synced twice daily from Amazon, Best Buy, and Newegg. It exists to answer one question well: which product gives the most capacity, screen, or pages per dollar right now.
